Title: Optical head position detecting device
Inventor: IZUMI YASUHIKO
IPC: G11B7/085
Filed: 1986-10-20
Abstract: PURPOSE:To detect the position of an optical head with high accuracy, by providing a timing pattern on a slit plate where a code pattern is formed, and detecting the code pattern with the timing of the slit of the timing pattern. CONSTITUTION:When the optical head is moved by the operation of an optical disk device, the slit plate 3 is moved synchronizing with the optical head. At this time, a slit detecting device detects the slit patterns of a Gray code 3a and the timing pattern 3b. And it detects the Gray code 3a at the trailing edge timing of the slit detecting signal of the timing pattern 3b. In other words, since a detected Gray code is always detected at a constant position (the position of the timing pattern whose detected waveform is stable), it is not affected by the difference of the detected waveform of the Gray code generated by variance in an element or a light receiving circuit. The detecting signal of the Gray code 3a is converted, for example, to a binary code at a code conversion circuit, and inputted to a control part, then, the position of the optical head is decided at the control part.

Filed: 1994-10-14
Abstract: PURPOSE: To permit the maintenance of normal combustion by a method wherein the zero point of an air volume sensor is corrected by an air volume information operated based on the measured value of output of the air volume sensor to control the rotation of a combustion fan. CONSTITUTION: When the recording data of measured values of output of an air volume sensor 18 are sent sequentially from an output judging unit 42, an output fluctuating amount judging unit 44 selects the maximum value and the minimum value among the recording data and sends out the recording data of a predetermined number as the data for correction when a difference between the maximum value and the minimum value is within a set fluctuation width of output and the number of recording data, sent sequentially, coincides with a predetermined number. A zero point correction operating unit 46 operates the average value of the sent data for correction and outputs the average value as the zero point correcting value for the air volume sensor 18.  The air volume in an air flowing passage is operated based on the measured value of the output of the air volume sensor 18, whose zero point is corrected, while the rotation of a combustion fan 12 is controlled by the operated air volume informations.

Title: Changeover type interphone
Inventor: TANIGAWA YOSHIHIRO
IPC: H04N7/18
Filed: 1989-09-26
Abstract: PURPOSE:To dispense with a countermeasure for heat generation in a repeater by supplying a DC power source which becomes the power source of a slave in a constant current from a master connected to the slave and supplying a DC voltage in a constant voltage from the master to which a signal from the slave is distributed. CONSTITUTION:A switch SW2 is closed when the master J is operated. The common contact C of a change-over switch SW1 is connected to a normally-closed contact NC ordinarily. Therefore, direct current from the DC power source 85 is made into the constant current with a constant current supply means 86, and it is supplied to a transmission line via the SW1 and a balancing input/output circuit 9. Also, when the rise of the inter-line voltage of the transmission line is detected with an open detection circuit 7, the contact C of the SW1 is connected switchably to a normally- open contact NO, therefore, the constant voltage is supplied from the power source 85 to the transmission line via a resistor 87. At a state where the master J1 is directly connected to the slave and the signal from the slave is distributed to another master J2 via a buffer amplifier 53, the direct current supplied from the master J1 is consumed at the slave, however, the direct current supplied from the master J2 is consumed at neither the slave master nor a repeater K.

Title: Fluorescent lamp and lighting system
Inventor: SAKAKIBARA YUICHI
IPC: H01J61/52
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To provide a fluorescent lamp offering satisfactory luminous efficiency, even in a closed-type luminaire and a lighting system using the same. SOLUTION: A phosphor layer 2 is formed on the inner surface of an oblong light- transmitting discharge container 1, an ionizable medium including mercury and rare gas is sealed up inside thereof, a pair of electrodes 3 are sealed in both ends thereof. A heat insulator is disposed in a position between one end of the light-transmitting discharge container 1 and one electrode 3. The mounting height of the one electrode by which the heat insulator is disposed is made larger than that of the other by 5 mm or larger. Because a coldest part is formed in the end part of the light-transmitting discharge container where the heat insulator is disposed, when temperature rises in a middle part of the light-transmitting discharge container, luminous efficiency is less liable to be lowered. Because the length of a discharge path is inhibited from shortening, optical output is easily secured.  If an electrical insulation material is used for the heat insulator, it can be supported by a pair of internal lead wires put through it. If a light-transmitting material is used for the heat insulator, if a phosphor layer is formed thereon, or if an ultraviolet-transmitting property is given thereto, a dark spot in the end part of the light-transmitting discharge container can be eliminated or reduced, which will be formed if the heat insulator is metallic.
